Rejoice o Harry Potter fans like me! J.K. Rowling has done it at last; she has revealed on her website that the 7th and final installment of the Harry Potter series - "Harry Potter and the Deathly Hallows," will be published across the world on July 21 - a time to be marked by celebrations and more than a few tears, as Rowling wraps up the magical adventures of the boy wizard, his friends and his enemies.

Potter readers have a lot to look forward to, and to fear. Rowling has said two characters die in the final book and fans are wondering whether Harry is one of them. When asked about Harry's fate, Rowling has said she could understand authors who killed their characters off, to stop others writing new adventures.

But she admitted being worried about the reaction from fans if the boy wizard came to a sticky end.

Rowling always made it clear the series would be in seven parts and much of the plot was almost set in stone. In a recent web posting, she said: "I'm now writing scenes that have been planned, in some cases, for a dozen years or even more."

The print run and number of pages have yet to be revealed, but judging from the suggested cover price, a meaty $34.99, $5 more than Potter 6, ``Harry Potter and the Half-Blood Prince,'' the last book will likely match or exceed the 600-plus page length of previous releases.

"We have held the price for the past four years,'' Scholastic publicist Kyle Good told The Associated Press. "In that time, costs of production, paper, trucking, gas and security - to be sure all readers can enjoy the book at the release time - have all increased.''

The Potter books have sold over 325 million copies worldwide, have been translated into 64 languages and churned five blockbuster movies.

This is the 10th anniversary of the first book of the hugely popular series being published.
